Site Works Aug 22-26






Work has been progressing all week on the brickwork corner buttressing as this needs to be in place prior to completing the dome. Work has been slow due to the high number of specials where the brick meets the arches, but we are almost over the hump(s). The dome has arisen in each of the corners but will begin in earnest next week. Thank you to all who have been putting in the hard hours on the brickwork, especially - Carthage, David, Mark, Bruno, Alex, Ian, Elaine, Rae, and Suzy.

Site works - 20th and 21st August

We've completed the arches and have started work on the dome. The key thing for the coming week is to keep the brick rising walls ahead of the dome, as we cannpt complete the dome until the walls are in place.
We used the lower course of the arches as a test for getting the placement of the slips right for the dome - and so used casting plaster to allow us to perfect the mixing of small amounts of plaster (enough for one slip) to the correct consistancy quickly. This will be critical for the dome as we will be relying on the plaster to set quickly and to hold each slip in place as we work upward.

Site Works - 19th August

Laying bricks continued and we passed the 11th course on all piers. This means that the angle of embrace for the arches is now less than 52 degrees for the remainder of the arch. This will allow us to complete the brick slip portion of the arches and get going on the dome. The remainder of the brickwork will follow on over the next few days to its completed state.
The beam across the top of the site is part of a setting out methodology for the dome that we will be testing tomorrow. It replaces our initial idea to use a central pole. Once we have the system working correctly we will document it here.

Ecocem

Many thanks to Ecocem who have provided a significant quantity of cement for the project, which we are mixing with Portland cement as required. Ecocem is bascially GGBS, and using this reduces the carbon footprint of our project by substituting a by-product of industrial processes for cement that is made locally and consumes a significant amount of energy in its manufacture.

Site Works - 18th August

Works today took the walls to 7-8 courses high.

Site Works - 15th August

We continued bricklaying and building the arches today as was the case last Friday. Work was still slow but we managed to get to the 5th course on each pier, so we are getting a bit faster. We're taking tomorrow (Sunday) off and will continue where we left off on Monday.
